Having thought a bit about it, one motivation for choosing the route I did; rather than the more idiomatic one; is that it relies on pipeline of source transformations to get to optimal code. The initial expansion is often pretty sloppy. I don't do many source transformations, everything is designed to emit pretty optimal byte code on the first pass.
